207 Vibration-Damped Marine Barograph
Aneroid barographs are used to measure and record the history of atmospheric pressure.
This beautifully crafted Fischer ‘Captain’s Choice’ barograph is housed in a beech hardwood with a mahogany stain finish. The measuring element is a set of 7 aneroid capsules, manufactured of a copper-beryllium alloy that essentially eliminates age-hardening, hysteresis, and elastic after effects that could otherwise degrade the accuracy of the instrument.
This range of Fischer barographs have a vibration-damped movement for use at sea with a fixed measuring range of 955-1055 hPa.
207MQ - movement is steel, with flat chrome finish
